Craftsmanship & Technical Specifications
Atelier Description & Craftsmanship
The Rolex Cosmograph Daytona 116500LN 40mm Black Dial Clean Factory (Catalog Ref. RLX-DAY-116500-BK-CF) represents Clean Factory‘s latest production batch, combining Solid 904L Oystersteel (Satin & Mirror Finished) construction with the 28,800 vph Dandong DD4130 / SH4131 Integrated Chronograph. With 40MM × 12.2mm (1:1 Case Profile) proportions and 72-Hour Extended Reserve (28,800 vph), it delivers the exact visual depth and mechanical cadence collectors look for.
Inside the Dandong DD4130 / SH4131 Integrated Chronograph Architecture
Pay close attention to the transitions between brushed and polished surfaces along the case flanks and bracelet center links; each edge is hand-finished after CNC milling. A colorless anti-reflective sapphire crystal seals the dial against dust and moisture.
